Research on satellite's co-layout method with structure and thermal design under heterogeneous CAD

Satellite's layout is a system engineering involves multi-system and multi-department collaborative design, which needs times' iteration and coordination. Due to the different work background, state of satellite layout need to interact between heterogeneous CAD model, the present method mainly depends on artificial operation. With satellite's state becomes more and more complex, the method is easy to bring information lost, version's mistake. Besides, long time consuming, low efficiency, and high leakage risk, directly affects the development of the project. On the basis of isomorphic CAD, this paper proposes a parameterization method to express the whole layout state in the mode of collaborative work with structure design and thermal design, which uses forms as a tool to transfer layout state instead of 2D or 3D model to improve the efficiency of collaborative work.
